WHEELED CUL'IVATOR.

Application filed December 13, 1921.

To all whom may concern:

Be it known that I, JOHN B. SWAN, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Wheeled Cultivators, of which the following is a specification.

rllhe presentinvention is directed to improvements in cultivators, and more particularly the hand wheeled type.

The primary object of the invention is to provide a device of this character constructed in such a manner that a person can with ease propel the device across the field.

A further object of the invention is to provide a cultivator of this type having a frame so constructed that the cultivator tooth supporting frames can be conveniently detached, and plows and their associated beams substituted.

A still further object of the invention is to provide a cultivator having a frame which can be adjusted laterally so that plants in rows of varying widths may be cultivated.

Vvith these and other objects in view this invent-ion resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which is shown a perspective view of the device, showing the cultivators in place.

The device comprises a frame 1, which consists of upper and lower vertically spaced bars 2 and 3, respectively, and front and rear vertical supplemental frames 4 and 5, respectively. rllhe front frame is formed from a single length of suitable metal, and comprises a horizontal bar 6 and vertical side bars 7, the lower ends of which terminate in horizontally disposed axles 8, and upon which are rotatably mounted ground wheels E). The rear frame consists of sections 10 and 11, each section comprising a horizontal bar 12 and 13, respectively, which are adapted to overlap and are provided with slots 14 which register. A pair of clamping bolts 15 are engaged in these registered slots and serve to hold the sections in adjusted positions.

The bars 12 and 13 each terminate in a vertical bar 16, the lower end of which terminates in a horizontal foot 17, the purpose of which will appear later. A perforation 18 is formed in each foot.

Serial No. 522,025.

rlhe upper bars 2 have their forward ends secured to the vertical bars 7 of the frame 4, while their rear ends are secured to the vertical bars of the frame 5. The forward ends of the bars 3 are provided with perforations which receive the axles 8, thus connecting these bars with the front frame.

Adjustably mounted on the vertical bars 16 are clamps 2O in which the handle bars 21 are engaged. The forward ends of the handle bars are provided with perforations 22, which engage the axles 8 flush with the forward ends of the lower bars 3. Thus it will be seen that pressure on the handle bars 21 will be imparted to the axles 8, and consequently the forward part of the frame 1, thus permitting the device to be pushed with comparative ease. By providing the clamps 2O the handle bars 21 may be conveniently swung upwardly or downwardly to suit persons of different statures.

The cultivators used in connection with the above described frame, two of which are employed, are preferably of the type shown, and consist of frames 23, said frames comprising parallel bars 24 pivotally connected at their ends by cross bars 25, the outer upper cross bars being provided with extensions 27, the purpose of which will appear later. Secured to the cross bars 24 between the bars 25 are bars 28 which have passing therethrough clamping bolts 29 adapted to detachably engage the perforations 18 in the feet 17, whereby the frames 23 can be conveniently attached to or detached from the feet. Links 30 are provided and have their rear ends pivotally engaged with the extensions 27, and their forward ends provided with hooks 31 adapted to selectively engage the holes 32 in the bars 3 of the frame. Two of these holes are shown, but it will be understood that the number may be increased if desired. Thus the links 30 5may be shifted to hold the frames 23 in the desired angular relation with respect to the line of travel of the device.

If desired the entire frame work of the device may be made from channel iron or the like to add strength and durability to the machine.

The teeth 38 are of the spring type, and are pivotally connected to the bars 24 of the frames, which is necessary since the bars are Capable'. of relative Swinging' niov'emeit. Vhat is claimed is l J wheeled... eulpivator `comprising in com:

bination, a frame coiisi'stili'g of affiolit alj'l' and a, rear arch secured together at' ez'ar'oli'v side by an upper and a lower` vside bar, tghe lower` extremities of said front arch being carried in wheels and the lower .extremities of said rear rarch loe-ing turned at an angle; olti'vato ,fleuries7 carrying oulti'vator plows, pivotd to said anigulxrly turned porltioiiS of sicl re'r areli ziiid lilmseored to each; of said cultvator frames at their one extremity and yacljvustbly engaging Y said lower ls their other exltremi'iy'l I' esti'mony whereof I have hereunto set mymhavnd in presence of two subscribing witnesses.
